spoffs: Offset Correction of a Matrix of Mid-infrared Spectra

In spftir: Pre-Processing and Analysis of Mid-Infrared Spectral Region

Description

Allows the removal of the background of a matrix of mid-infrared spectra.

Usage

Arguments

spectra

matrix. The matrix of FTIR spectra. The first row corresponds to wavenumber; the remaining rows corresponds to absorbances.

Value

A matrix spectra with with background values deleted. The first row corresponds to wavenumber; the remaining rows corresponds to absorbances.
